NASA has found water on a planet in our solar system's asteroid belt – and it could be home to alien colonies, scientists have revealed.

New images from Nasa’s Dawn spacecraft reveal the frozen water trapped in some of the craters where the sun never shines on dwarf planet Ceres.
Ceres' poles could have been collecting ice over billions of years, scientists claimed.

Ceres is the third planetary body, after the Moon and Mercury, where frozen water has been identified

And the ice in Ceres crust could point to a subsurface ocean, one of the key indicators of life.

It’s the third of its kind to get scientists’ excited.

Water ice has also been found on the dark side of the moon and Mercury, too.
